摘　　要：匀加速运动目标测距存在着非线性运算,给实现带来诸多不便。基于曲线逼近原理,提出了一种实用的径向匀加速运动目标下的测距方法,并对加速度的估计补偿问题进行了讨论,采用二次叉积法进行加速度估计,通过加速度补偿,将匀加速运动测距问题转化为匀速运动测距,从而大大简化了非均匀运动目标测距的实现。Nonlinear operations in the double-frequencies ranging made many difficulties to range for uneven-speed objects. The paper put forward an applied ranging method for even accelerated and rectilinear movement which based on the principle of curve approaching. And the estimation and compensation for the acceleration were discused. The acceleration was estimated by two-time cross product. Then ranging for uneven-speed objects was converted into ranging for even-speed objects, which simplified the realization of ranging for uneven-speed objects.
